RAILWAY-CAR TRUCK.

SPECIFICATION forming part of Letters Patent N0. 590,982, dated October 5, 1897.

Application filed April 16, 1897. Serial. N0. 632,461. (N0 11106.81.)

To LIZ who/11, t 111/111/ rfa/teaml- Be tknown that I, FRANK HEDLEY, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Railway-Car Trucks, of which-thefollowing is a specification.

My invention relates to railway-car trucks.

The object of my invention is to provide a railway-car truck of a simple, strong, and eflicient construction, which at the same time will afford a maximum amount of space or room for the accommodation of' electric, compressed air, or other motors that may be required to be mounted thereon between the car-axles and the transverse bolster-carrying plates.

'Ihe car* truck embodying my invention comprises in cooperative organization or combination, first, a pair of truck side pieces, each having formed integral therewith pedestal jaws or columns for receivingthe journalboxes of the axles, seats for the coil-springs, pillows or vertical columns or flanges to receive the cross-plates of the truck-bolster, and also traverse iianges at the ends thereof for receiving the end pieces of the truckframe second, the trucleframe end pieces secured to and stepped upon the ends of the truck side pieces.; third, a truck-bolster comprisin g a pair of cross-plates set edgewise and bolted or otherwise secured to the pillows or upright-column flanges on the truck side pieces, and taking a bearing at each end or top of the truck side pieces and alsonear the bottom of the pillows, and between which edgewise truck-bolster plates a swinging bolster is adapted to be received, these transverse truck bolster plates being tied together near their middle by filler castings or blocks;

fourth, a swinging bolster fitting betweenthe edgeyvise truck-bolster plates and supported by hanger-pins resting on top of the edgewise tru cli-bolster plates 5, fth, elliptic springs interposed between the swinging bolster and the supporting-bar beneath, which is connected to the hangers;` sixth, axle-boxes having extended flanges and provided with two spring-seats adapted to receive and surround the 'coil-springs at their outer ends; seventh, coil-springs setting on top of the spring-seats which are integral with the axle-boxes and received at their upper ends in the corresponding springseats that are integral with the truck-frame side piecesthe integral pedestaljaws on the truck-frame side pieces projecting down through suitable openings formed in the axle-boxes.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described, and specified in the claims.

. In the accompanying drawings, forming a part of this specification, and in which similar letters of reference indicate like parts in all the views, Figure 1 is a plan view of a railway-car truck embodying my invention, for convenience only one side or half of the truck being shown, the other duplicate half or side of the truck being omitted. Fig. 2 is a side elevation. Fig. 3 is a central vertical transverse section on the line 3 3 of Fig; 2. Fig. 4. is a detail section on the line 44 of Fig. 3. Fig. 5 is a detail plan view of the axle-box, showing the coil-spring seats formed integral therewith and the pedestal-jaws in horizontal section. 6 is a detail section on the line 6 6 of Fig. 5;4 and Figs. 7 and 8 are detail sections of the truck side piece on lines 7 7 and S 8, respectively, of Fig. 2.`

In the drawings, A A represent the wheels of a car-truck, and Al A the axles. The truck side pieces B are formed of cast-steel and have cast integrally therewith, and forming a part thereof, pedestal jaws or columns l) b s ring-seats b' b' central illows or vera p a a p tical columns or flanges b2 b2, and transverse flanges b3 at their ends. The truc-.k side pieces B also have integral tie or brace members h4 integrally uniting the lower ends of the pillows b2 with the side piece B. The side piece B is preferably of' an I or double-channel-bar form in cross'section, as indicated at b5 in Fig. 3 and also in Fig. 7, and the brace member b4 is preferably of a Tform in crosssection, as indicated in Fig. 8.

C C are the end pieces of the trucloframe.

the transverse end flanges h3 of the truck side piece B at the ends thereof. The truck side `They are preferably of T form in cross-sec- `tion and are secured by bolts or rivets c to IOO pieces B are also preferably provided with steps or shoulders b to receive the inner flange c' of the truck end pieces C, so that the truck end pieces C may thus rest directly upon the truck side pieces B, as is clearly in.- dicated in Fig. 2. The truck side pieces B and end pieces C are further secured together and strengthened or braced by an angle-plate C' at each Corner, secured thereto by bolts or rivets c2.

The truck-bolster consists of a pair of flat plates D D, set edgewise and at a sullicient distance apart to receive the swinging bolster E between them, and which are secured at their ends by bolts or rivets d to the pillows or vertical columns or flanges b2 of the truck side piece. The truck-bolster plates D also project over and take a bearin g directly upon the truck side pieces B at d, the bolsterplates D being preferably provided with notches d2 to receive the truck side piece B. The truck-bolster plates D also take a bearing at their lower edges directly upon the truck side pieces B, near the lower end of the pillows b2 thereof, the pillows b2 being provided with shoulders la7 for this purpose, as will be clearly understood by reference to Figs. 2 and 3. The swinging bolster E is adapted to swing endwise and also freely up and down in the space between the upright or edgewise standing truck-bolster plates D D. The swinging bolster preferably consists of a pair of channel-bars c e, secured together by flat plates e', riveted to the flanges of the channel-bars.

The swinging bolster E is supported upon elliptical springs F, which rest upon the hanger-bar F, and which is supported by the hangers F2 from the hanger-pins F3, which rest directly upon the truck-bolster plates D D. The hangerpins Fs are preferably squared or flattened where they rest upon the truck-bolster plates D, and the bolsterplates D are provided, preferably, with notches or seats d3. The han ger-pins F3 are of course round at the points where the hangers bear thereon.

The truck-bolsterplatesD D are secured together and braced or strengthened near their middle by castings or filler-blocks D', which are secured or bolted thereto, as illustrated in Fig. 3.

D3 is the center plate, and D4 the pin connecting the center plate to the swinging bolster.

D5 D5 are side bearings or rests, which are preferably secured to the swinging bolster for the car-body bolster to strike against and limit the swaying movement of the car-body.

G is the axle-box. It is provided with lateral integral extensions g and a pair of springseat-s g g', adapted to receive and embrace the lower ends of the coil-springs H, just as the corresponding spring-seats b' on the truck side pieces receive and embrace the upper ends of these coil-springs.

The coil-springs l-I H thus lit between and are compressed between the integral spring-seats formed on the axle-boxes G and the corresponding integral spring-seats formed on the truck side pieces. No bolts or other fastenings are thus required for securing any of the spring-seats in place, and the springs themselves are held in position by the flanges or walls g2 bs, surrounding or forming part of the spring-seats. The axlebox G is provided with openings g3, one on each side of the axle, to receive the pedestalcolumns Z9 b on the truck-frame side pieces B. The pedestal columns or jaws b b thus pass through the journal-boxes G. The pedestaljaws Z9 b are tied together at their lower ends by a flanged or shouldered bottom plate bu, secured thereto by bolts b, furnished with keys Z110.

The spring-seats l) 1)/ on the truck-frame side pieces, it will be seen, are formed thereon by simply increasing the depth vertically of the lower flanges of the channel-bars forming said truck side pieces and swelling and rounding out said flanges into circular form, so to speak, so that the effect thereof is not to weaken, but, on the contrary, to strengthen and reinforce, the truck side pieces at those bearing-points.
